Q.Assertion (A) : The most suitable method of printing with disperse dyes is transfer printing Reason (R) : Disperse dyes sublime when heated to high temperature Codes
Correct answer: Both (A) and (R) are correct
Explanation
Disperse dye are the organic colouring substances which are free from ionizing groups, are of low water solubility and are suitable for dyeing hydrophobic fibers. Since they are insoluble in water they sublime when heated to high temperate. The most suitable method of printing with disperse dye is transfer printings.
